Need to solve.For example, the first, electron emission problems of carbon nanotube cathod.On the one hand, the making area of carbon nanotube layer is not also
It is sufficiently large.It is envisioned that carrying out electron emission without sufficient amount of CNT, active display is can not to obtain enough
Anode working current.Only the making area of carbon nanotube layer becomes big, can allow sufficient amount of CNT all
Participate in field-electron emission.But the making area of carbon nanotube layer can not be excessive, otherwise will cause the display of active display
Resolution ratio declines.On the other hand, in carbon nanotube layer, not all CNT has been involved in field-electron emission, has
CNT can launch a large amount of electronics, and some CNTs can only launch a small amount of electronics, or even the CNT also having is basic
Just there is no launching electronics, the manufacture craft of this and carbon nanotube cathod, making structure etc. have relation, it is also necessary to are largely ground
Study carefully exploration.Second, gate pole control ability problem.The essence for setting gate pole is exactly the electron emission for controlling carbon nanotube layer
, but the gate pole control ability at present in active display is all weaker.Typical technology index be exactly gate work voltage it is very high,
Gate current is excessive.In terms of improving and improving gate pole control ability, it is necessary to from gate structure, the manufacture craft of gate pole, gate pole
The everyway such as making material improved, this also needs to be explored.Third, the cost of manufacture problem of active display.
One successful display, it should develop towards low cost, high quality direction.If the cost of manufacture of active display is too high, it is
The requirements for sale in market can not be adapted to show at present.The presence of these technical barriers, it is also necessary to research and develop and make great efforts to solve.

Beneficial effect：The present invention possesses following significant progressive：
First, it is described it is double before it is flat after during Qu Zhengyuan solely gate two ribs point side straggly cathode construction, made it is double before it is flat
Qu Zhengyuan gate poles afterwards.After appropriate operating voltage is applied on gate pole, strong electric field will be formed in CNT layer surface
Intensity, on the one hand forces CNT can carry out electron emission, the number of another aspect CNT institute launching electronics quantity
It can change with the change of gate work voltage.This embodies double preceding flat rear Qu Zhengyuan gate poles to the strong of carbon nanometer layer
Control performance.In double preceding flat rear Qu Zhengyuan gate poles, three layers of one layer of the right and wrong electrode of gate pole and the right and wrong electrode of gate pole are planar shaped, main
It is used to form strong electric field intensity in CNT layer surface, due to its flatness, can further reduces gate pole-carbon nanometer
Coverage between tube cathode, so as to reduce gate work voltage；Four layers of two layers of the right and wrong electrode of gate pole and the right and wrong electrode of gate pole
For curved, it is mainly used in transmitting extraneous work potential, due to its curved, can reduces to exhausted between gate pole-cathode
The requirement of edge material property, it so can further reduce the cost of manufacture of active display.

The carbon nanotube layer of two layers of electrode layer of one layer of electrode layer and negative electrode rib point bottom outside has very big on the outside of negative electrode rib point bottom
Anchor ring edge.It is well known that " fringe field enhancing " phenomenon in Flied emission active display be present：In anchor ring marginal position
Electric-field intensity can be further enhanced.So, the CNT positioned at anchor ring edge just obtains bigger electric-field intensity, from
And more electronics can be launched.Because two ribs point side straggly negative electrode has very big anchor ring edge, then CNT can
Launch more electronics, that is, very normal thing, this is for further improving the anode current of active display, improving
The luminosity of active display is favourable.
3rd, in described double preceding flat rear Qu Zhengyuan solely gate two ribs point side straggly cathode construction, prepared by CNT
On the outside of the negative electrode rib point bottom on the outside of one layer of electrode layer and negative electrode rib point bottom on two layers of electrode layer.Due to one layer on the outside of negative electrode rib point bottom
